    paper Kronos

    Overview

    Kronos is a productivity tool designed to help users reach flow state, by aligning tasks with organically evolving mindsets and with layered personal goals.

    It is a long-lived passion of mine, to make a computer understand human time and goals, in order to be a companion who is aware of our most valuable asset: time.

    Aside from my research in turning flow-state and well-known time management paradigms into an algorithm, Kronos draws from my personal life as I learn how to juggle my goals, everyday life, and my obstacles, and observe useful or bad patterns.

    ![Kronos Timeline](https://www.twine.net/signin

    Key Features

    Task Scheduler Algorithm

    Automatically schedules tasks into ideal calendar gaps using constraints like:

    • Preferred time of day (morning, afternoon, evening)
    • Ideal days of week
    • Repetition rules (daily, weekly, hourly)
    • Time durations

    Avoids overlaps with existing events using a gap-finding and conflict resolution strategy.

    Dynamic Modal Routing

    Uses Next.js searchParams to open modals for editing tasks/events while preserving the current route.

    Modals behave like overlays but retain full routing capabilities.

    Animated, color-coded UI

    The UI si designed with a dynamic accent colour, reflective of the ongoing task.

    Transitions and animations are created with Framer Motion

    Reusable Input System

    MultiSelect, DateTime, and Mindset selectors are modular React components, fully controlled via props and Redux state sync.

    Calendar component built with Hexaflexa library

    Markdown editor built with TipTap

    Architecture and Engineering Highlights

    Monolithic App with Modular Domain Separation

    • /app - routing and pages
    • /components - client-side UI and forms
    • /lib - database interface, shared types, utilities

    Database (PostgreSQL + Prisma)

    Uses Next.js searchParams to open modals for editing tasks/events while preserving the current route.

    Modals behave like overlays but retain full routing capabilities.

    Next Steps

    • Implement an 7-layer system of tracking goals and determining emerging priority, tied to humans’ perception of time: from life goals down to work sessions.
    • Connect to Notion API, to make use of the world’s most versatile personal data organisation tool.
    • Train a custom ML model that learns from weekly patterns and offers suggestions accordingly.
    • Build a React Native version, to be used and tested as a mobile app.
    • Come up with ways to gather data about the user’s time, without needing direct input. The need for abundant and constant input is of the biggest hurdles for such a tool.
